1.We choose ≥Mg99.95 of GB3499- 2003 for rare earty alloy.2. rare earth Ca/RE≥99.95%.3.Using special crucible in the process of production and gas
protection to strictly control the impurity content.4.Small ingot and large surface area, uniform composition, no need
to be broken and easy to melt.

Directions for use

According to the customer request to add rare earth alloy. Removing
Packaging shrink film first and preheat to 300 ℃. After adding all
alloy, raise temperature to 750 ℃ + / - 5 ℃ and stirring.

Note: Please choose earth special flux as refining flux .

Application

Adding Calcium before die-casting can reduce the oxidation of the
melt, and refine alloy grain, and improve the rolling of sheet. The
presence of calcium can also reduce the micro battery effect of
magnesium alloy.

The Function of Master Alloy:

1.Grain Refiners

Control the structure and dispersion of individual crystals in
metals

Improved mechanical strength and soundness of the casting

2.Modifiers

Change micro-structural properties of metal

Increase strength, toughness, ductility, and resultant
machinability.

3.Hardeners

Change composition of metal alloys

Specifications:

Regular type:MgCa5-20%

Application:

1. Refine the grain apparently,restrain the oxidation of melting
metal.

2. Add temperature:750℃±5℃

3. add quantity :0.3%max

Our alloys enable casting houses and ingot manufacturers to
overcome problems associated with alloying that they may experience.
